Hi David,

Ok, now I'm really lost! This is definitely due to my newbie git status but I'll ask anyway. I'm confused by your statement "... if you try to have one filesystem, with multiple people running git on their machines against that shared filesystem, I would expect you to have all sorts of problems."

Isn't that the whole point of git, or any versioning system? I thought the idea was that each developer installed git locally on their machines and (as needed) committed their changes to the master repository which resides externally to any of the local machines, such as on a network server (and which I'm assuming has git installed locally as well).

What am I missing?

The 'other' David Lang   ;-)

I think the risk is that if you have multiple people doing actions on the shared filesystem you can run into trouble.

As long as only one copy of git is ever running against the repository, I don't see any reason for there to be a problem.

But if you try to have one filesystem, with multiple people running git on their machines against that shared filesystem, I would expect you to have all sorts of problems.
